Replacement-free long-acting reference electrode capable of supplementing liquid for detection

Abstract

The long-acting reference electrode comprises a water injection cylinder and a copper sulfate reference electrode cylinder, the water injection cylinder is located on one side of the copper sulfate reference electrode cylinder, a water supplementing opening is formed in the top of the water injection cylinder, and the bottom of the water injection cylinder communicates with an adjustable water outlet; a copper electrode is arranged at the top of the copper sulfate reference electrode cylinder. The problems that the copper sulfate reference electrode cylinder loses efficacy, cannot be reliably connected with the ground, is suspended, is polluted and the like due to insufficient copper sulfate liquid can be effectively solved, and compared with a traditional copper sulfate reference electrode cylinder, the copper sulfate reference electrode cylinder has the advantages of being capable of supplementing liquid, free of replacement, easy to maintain, reliable in quality and the like; the copper sulfate reference electrode cylinder is designed with a fixed installation mode, and has important significance for ensuring stable output of a constant potential rectifier, improving cathode protection potential measurement accuracy and reducing operation cost.

Description

technical field [0001] The invention belongs to the technical field of long-acting copper sulfate reference electrode cylinders, and particularly relates to a long-acting reference electrode that can be replaced with liquid for detection and is free of replacement. Background technique [0002] At present, there are three main problems in the operation of the long-acting copper sulfate reference electrode cylinder: [0003] 1. Long-acting copper sulfate reference electrode cylinder CuSO 4 The problem of insufficient saturated solution, the main reason is CuSO 4 The copper sulfate reference electrode cylinder increases with the buried service life, and is affected by the temperature field around the pipeline, the sealing of the equipment itself, the corrosive environment, etc., which will accelerate the CuSO in the electrode. 4 Due to the leakage of saturated solution, CuSO cannot be installed and supplemented due to the limitation of the structure of the copper sulfate ref...

AI Technical Summary
